I wonder what kind of card Peter's using and if there is a potential linkage there. We've got the Sun branded Emulux cards in our sparcs. I also wonder if Peter were able to allocate an additional LUN to his system whether or not he'd be able to create a pool on that new LUN.
I'm not sure why exactly they were chosen over the qlogic, some of our admins swear by the qlogic cards, others have have had bad experiences with the qlogic cards not allowing for persistent binding on some configurations, but from my perspective being mostly a SAN noob it's all hearsay. -- Sean M.

Odd. I've got PowerPath working fine with ZFS with both Symmetrix and Clariion back ends. PowerPath Version is 4.5.0, running on leadville qlogic drivers. Sparc hardware. (if it matters) I ran one our test databases on ZFS on the DMX via PowerPath for a couple months until we switched off of it because of the 'bogus memory usage' statistics problem. We still use it on a server we use for logs processing and retention that uses the Clariion as a back end. cheers, Brian On Jul 13, 2007, at 11:08 AM, Alderman, Sean wrote: > There was a Sun Forums post that I referenced in that other thread > that mentioned something about mpxio working but powerpath not > working.
